Support total clean counter for Roborock devices

When Roborock was officially migrated into core ( MR #89456 ) we lost the total clean count sensor which was pretty handy. This request is to get that sensor re-added :slight_smile:

Completed here: Add total cleaning count sensor to Roborock by Lash-L · Pull Request #135015 · home-assistant/core · GitHub

Thanks for the suggestion!
